Various valuable diamonds around the world have been mysteriously disappearing, so West and Gordon are charged with ensuring that an upcoming international jewel exhibition goes off smoothly. Upon investigating some mysterious doings at the house of one of the exhibitors, they come across Morgan Midas, who has invented a way to make himself move so quickly that he becomes invisible.
